Abstract: An electrical connector includes a plug portion and a receptacle portion. The plug portion includes a plurality of conductive pins, with a portion of each conductive pin surrounded by a non-conductive post. The receptacle portion includes a plurality of conductive pins recessed into a corresponding plurality of recesses within the receptacle portion. When the plug portion is mated to the receptacle portion, the conductive pins of the plug portion are received within the recesses of the receptacle portion and electrically connected to the conductive pins of the receptacle portion. To advantageously increase creepage and clearance between pins, it is desirable for each recess to have a depth sufficient to receive both a conductive pin and a corresponding surrounding non-conductive post when the plug portion is mated to the receptacle portion.

Abstract: Systems and methods for electroporation catheters are provided herein. An electroporation catheter includes a shaft, and a variable diameter loop coupled to a distal end of the shaft, the variable diameter loop including a plurality of electrodes. The catheter further includes a plurality of electrical wires connected to the plurality of electrodes and extending through the variable diameter loop and the shaft, the plurality of electrical wires configured to energize the plurality of electrodes, and a multi-lumen arrangement extending through at least a portion of at least one of the shaft and the variable diameter loop. The multi-lumen arrangement includes a first lumen housing a first subset of the plurality of electrical wires, and a second lumen housing a second subset of the plurality of electrical wires.

Abstract: A method of authenticating devices utilizes a central ledger distributed to a plurality of local systems includes storing a unique identifier locally on each device, modifying a central ledger to include an entry associated with the unique identifier and communicating the central ledger to a plurality of local systems for storage. To authorize a device, the local system receives a unique identifier from a connected device and searches the local ledger to verify/authenticate the validity of the connected device for use in the local system. The local system may then modify an entry in the local ledger associated with the unique identifier to reflect use and communicate the modified local ledger from each of the plurality of local systems to the centralized system. The central system then modifies the central ledger based on the received local ledger and communicates the modified central ledger to a local system.
